  Hereinafter, the technical technique in the embodiment of the present invention will be described clearly and completely in conjunction with the drawings in the embodiment of the present invention, but the described embodiment is only a part of the embodiment of the present invention, and all It is clear that this is not an embodiment. All other embodiments obtained under the premise that a person skilled in the art does not perform inventive work based on the embodiments of the present invention belong to the scope protected by the present invention.

  According to an embodiment of the present invention, before charging or discharging (power feeding to a load) of a battery, the battery is placed in a battery box that can store the battery and can be heated and kept warm. The battery to be discharged is preheated, and the temperature is intelligently adjusted in the preheating process so that the temperature of the battery finally becomes suitable for safe charge and discharge.

The method according to an embodiment of the present invention can be realized by a controller capable of performing temperature control, specifically, The method of the embodiment of the present invention includes the following.

S101: When preheating the battery, the environmental temperature value of the preheating region is acquired.

  The preheating region may be a region surrounded by a chamber inside the apparatus that can store a battery that is waiting for preheating and that can be heated and kept warm, and this region is a sealed region that holds a preheating temperature after inserting the battery. can do. Specifically, FIG. 9 can be referred to for this region.

  In the process of battery preheating, a temperature sensor placed in the preheating region can be used for real-time monitoring to obtain the temperature of the preheating region, and the heating assembly can be controlled based on the monitored temperature.

  Specifically, a step of determining whether or not preheating is necessary may be further included before the step S101, and the environmental temperature at the current position is acquired by a temperature sensor or by searching for a weather temperature or the like on the Internet. When the environmental temperature is lower than a predetermined threshold value (for example, 0 degree), S101 is executed.

S102: When the environmental temperature value of the preheating region does not satisfy the predetermined temperature condition, the current temperature of the preheating region is adjusted until the environmental temperature value of the preheating region detected again meets the temperature condition.

  The situation where the predetermined temperature condition is not satisfied is that the environmental temperature value of the preheating region is not within the temperature range indicated by the temperature condition, that is, the environmental temperature value is lower than the minimum value indicated by the temperature condition. Or higher than the maximum value indicated by the temperature condition.

  The temperature adjustment of the current preheating region is to increase the heating temperature when the environmental temperature value is lower than the minimum value, and when the environmental temperature value is higher than the maximum value indicated by the temperature condition, The lowering of the heating temperature generally involves gradually decreasing the temperature by using a method of turning off the heating power source.

  Specifically, when the heating assembly is turned on when lower than the minimum value, the heating assembly is started to operate and controlled to raise the temperature of the preheating region, and when the heating assembly is higher than the maximum value, Is turned off (the power is turned off) and the heating assembly is deactivated and controlled so that the temperature in the preheat zone does not rise again. The battery box material corresponding to the preheating region may use a heat insulating material to reduce the heat dissipation rate and save electric energy.

  A battery waiting for preheating may be used as a power supply, and power may be supplied to the heating assembly of the battery box in which the preheating region is located. It may be connected to an external power source via a power line to supply power to the heating assembly of the battery box where the preheating region is located. In addition, the battery box itself in which the preheating region is located may include a battery assembly. The battery assembly may not only provide power for preheating, but also after completion of preheating of a battery waiting for preheating as a standby power source. The battery can be charged as required.

  Heating may be stopped after the temperature of the preheating region reaches the temperature range indicated by the temperature condition. Alternatively, after the temperature in the preheating region reaches the temperature threshold indicated by the temperature condition, the heating is stopped, and specifically, the temperature threshold is within a predetermined temperature range and is close to the maximum value in the temperature range. Or an equal temperature threshold.

  Further, the preheating area may be an area surrounded by a chamber inside a battery box of an aircraft, intelligent robot, etc., and before inserting a battery and supplying power to the aircraft, intelligent robot, etc. (battery discharge), A preheating operation is executed, that is, the above-described S101 and S102 are executed. Monitoring and adjustment of the temperature in the preheating area may be performed by sensors, controllers (flight controllers, movement controllers), and the like arranged in equipment such as aircraft and intelligent robots.

  Embodiments of the present invention can not only pre-heat the battery if necessary, but can continue to detect the pre-heating environment until pre-heating is completed, and not only can realize the effectiveness for battery pre-heating, Adjustments can be made based on the temperature of the preheating region, and under conditions where preheating is guaranteed, electrical energy can be saved and battery preheating automation and intelligent requirements can be met.

  Further, FIG. 2 is a flow schematic diagram of the battery preheating method according to the embodiment of the present invention, and the method according to the embodiment of the present invention can be realized by a controller capable of performing temperature control. The method of the embodiment of the present invention includes the following.

S201: When a trigger event for battery preheating is detected, heating of the preheating region is controlled.

  Specifically, determining that a trigger event for battery preheating has been generated when an operating event is detected that the user has turned on the preheating function, for example when the corresponding physical button is turned on. Can do.

  Detection of whether there is a trigger event for battery preheating may be realized automatically. Specifically, it is detected whether a battery waiting for preheating is inserted in the preheating area. If there is a trigger event for battery preheating, it can be determined whether or not the battery is included in the preheating area by gravity sensing or distance sensing, and the following operation such as environmental temperature detection and adjustment can be started. May be included.

  Alternatively, the preheating circuit may detect whether current is being generated and, if so, may include the presence of a trigger event for battery preheating. After inserting a battery waiting for preheating into the preheating area, the battery supplies power to the preheating circuit in the heating module, and when it is detected that current is generated in the preheating circuit, there is a trigger event for battery preheating. And the following operations such as environmental temperature detection and adjustment can be started.

  Alternatively, it may be detected whether the environmental temperature of the preheating region is rising, and if it is rising, it may include the presence of a trigger event for battery preheating. After inserting a battery waiting for preheating into the preheating area, the battery powers the heating module and starts generating heat, at which time it detects that the temperature is rising and there is a trigger event for battery preheating. Then, operations such as environmental temperature detection and adjustment described below can be started.

S202: When preheating the battery, the environmental temperature value of the preheating region is acquired.

  Based on one or more temperature sensors provided in the preheating region, the environmental temperature value in the preheating region is detected and acquired.

S203: It is determined whether or not preheating of the battery is completed.

  Specifically, the step S203 may determine whether or not the recorded preheating time length has reached a predetermined time length threshold, and if so, the battery preheating has been completed. .

  The time length threshold can be determined after performing statistics on time data when the preheating is actually completed in a safe preheating temperature environment for a large number of corresponding types and volumes of batteries. In an embodiment of the present invention, the preheating time is The long threshold can be within 10-20 minutes.

  Alternatively, the S203 may include determining whether or not the acquired internal temperature value of the battery has reached a predetermined temperature threshold, and if it has reached, preheating of the battery is complete.

  The specific step of determining whether or not preheating is completed based on the internal temperature value of the battery receives the internal temperature information of the battery detected by the battery, and the received internal temperature information of the battery is a predetermined temperature. Including determining whether a threshold has been reached. The battery itself may be an intelligent battery that can detect the temperature of the cell, specifically the temperature of the central position inside the battery, and when the temperature reaches or exceeds a temperature value such as 5 degrees, No preheating is required and it can be determined that preheating is complete.

  As a result of the determination, if preheating has already been completed, the following S204 is executed, or the following S207 and S208 are directly executed. If not completed, the following S205 is executed.

S204: Stop preheating. The preheating is stopped by turning off the preheating power supply, and the completion of the preheating may be shown to the user by a method such as sound and light emission, and the subsequent battery charging / discharging operation can be performed.

S205: It is detected whether or not the environmental temperature value in the preheating region satisfies a predetermined temperature condition.

  If the temperature condition is satisfied, the process returns to S202, and the temperature detection step is executed again. If not satisfied, the following S206 is executed.

S206: When the environmental temperature value of the preheating region does not satisfy the predetermined temperature condition, the current temperature of the preheating region is adjusted until the environmental temperature value of the preheating region detected again meets the temperature condition.

  After adjusting until the temperature condition is satisfied, the process returns to S202, and the temperature detection step is executed again.

  In the heating process, the environmental temperature value in the preheating area is detected in real time, whether or not the temperature condition is met is determined in real time, heating can be stopped without delay, and the purpose of power saving and battery protection is achieved. To do.

  After the preheating is completed, the user may be informed that the preheating of the battery is completed by sound display, light emission display, vibration display, etc. Can be used. When the battery box itself corresponding to the preheating region is arranged as a charger or a discharger, the following steps may be further performed in order to satisfy the user's request for automation and intelligent charge / discharge. In the embodiment of the present invention, optionally, the following S207 and S208 may be further performed after the preheating is completed.

S207: When a charging trigger event for the battery is detected after completion of preheating of the battery, charging control for the battery is turned on.

  Specifically, the charging operation for the battery that has been preheated may be performed by charging the battery that has been preheated with a large-capacity power source or an external power source disposed in the preheating device.

S208: When a discharge trigger event for the battery is detected after completion of preheating of the battery, discharge control for the battery is turned on.

  The discharge trigger event includes a control event that is generated when a device such as an aircraft or a remote control robot receives a control signal such as a movement signal. In actual operation, when a control signal such as a movement signal is received, first, it is determined whether or not preheating is completed. If completed, S208 is executed to perform discharge.

  Further, the discharge trigger event may be a trigger event for automatically discharging protection of a battery that has been preheated and triggered by a user pressing a button. When the amount of electricity of the battery is relatively large, especially when fully charged, the battery's chemical activity is relatively high, and if it is not used for a long time, problems such as expansion and liquid leakage are likely to occur. In order to store the battery safely for a long time, the battery may be discharged according to the needs of the user, and at this time, the step S208 may be executed.

Specifically, adjusting the temperature of the preheating region in S206
When the acquired environmental temperature value of the preheating region is lower than the heat retention temperature threshold specified in the temperature condition, the heating of the preheating region is turned on, and the temperature of the preheating region is controlled to reach the heat retention temperature threshold. When,
When the acquired environmental temperature value of the preheating region is higher than the heat retention temperature threshold value instructed in the temperature condition, the heating of the preheating region is turned off, and the temperature of the preheating region is controlled to reach the heat retention temperature threshold value. When,

May be specifically included.

  In addition, in order to ensure that the temperature in the preheating area is uniform, a temperature sensor is placed at a specified position in the preheating area to obtain environmental temperature values at different positions, and multiple heating blocks are added to the heating assembly. The heating block which can be heated independently may be arranged in the area where each designated position is included. Specifically, acquiring the environmental temperature value of the preheating region in S202 includes acquiring the environmental temperature value of each predetermined characteristic position in the preheating region at the time of preheating the battery. In S206, the current temperature of the preheating region is adjusted when there is a characteristic position where the environmental temperature value does not satisfy the predetermined temperature condition. Including adjusting the temperature.

  Next, the battery preheating apparatus and apparatus of the embodiment of the present invention will be described in detail.

FIG. 3 is a schematic diagram of the structure of the battery preheating device according to the embodiment of the present invention. The battery preheating device according to the embodiment of the present invention can be used as a single preheating device or a mobile device such as an unmanned aircraft or a remote control robot. It may be a built-in battery box having a battery preheating function related to the embodiment of the present invention, or a combination of a battery box and a controller. Specifically, the battery preheating device includes:
A heating module 1 for heating the preheating region;
An acquisition module 2 for acquiring the environmental temperature value of the preheating region when preheating the battery;
When the environmental temperature value of the preheating region connected to the heating module 1 does not satisfy the predetermined temperature condition, the current preheating region is detected until the environmental temperature value of the preheating region detected again meets the temperature condition. A processing module 3 for adjusting the temperature;
including.

  The heating module 1 includes a heating circuit, and heats the preheating region with a resistor, a heating wire, or the like.

  The preheating region detected by the acquisition module 2 may be a region surrounded by a chamber inside the device that can store a battery waiting for preheating and can be heated and kept warm. It can be a sealed area that holds the preheat temperature. Specifically, the area shown in FIGS. 5 to 7 can be referred to.

  In the process of battery preheating, the acquisition module 2 can perform real-time monitoring to acquire the temperature of the preheating region by a temperature sensor placed in the preheating region, and control the heating assembly based on the monitored temperature.

  The situation in which the processing module 3 does not satisfy the predetermined temperature condition is that the environmental temperature value of the preheating region is not within the temperature range indicated by the temperature condition, that is, the minimum environmental temperature value indicated by the temperature condition. Lower than the value or higher than the maximum value indicated by the temperature condition.

  The temperature adjustment of the current preheating region by the processing module 3 is such that when the environmental temperature value is lower than the minimum value, the heating module 1 increases the heating temperature, and the environmental temperature value is indicated by the temperature condition. When the temperature is higher than the maximum value, it includes lowering the heating temperature, and the lowering of the heating temperature generally stops the heating using a method of turning off the power of the heating module 1 and gradually lowers the temperature.

  Specifically, when the processing module 3 is lower than the minimum value, the processing module 3 turns on the heating module 1, starts the operation of the heating module 1, and controls to increase the temperature of the preheating region. When the value is higher than the value, the processing module 3 turns off the heating module 1 (turns off the power), stops the operation of the heating module 1, and controls the temperature of the preheating region not to rise again. The battery box material corresponding to the preheating region may use a heat insulating material to reduce the heat dissipation rate and save electric energy.

  A battery waiting for preheating may be used as a power supply, and power may be supplied to the heating assembly of the battery box in which the preheating region is located. The heating module 1 may be powered by connecting to an external power source via a power line. In addition, the battery box itself in which the preheating region is located may include a battery assembly. The battery assembly may not only provide power for preheating, but also after completion of preheating of a battery waiting for preheating as a standby power source. The battery can be charged as required.

  The processing module 3 may stop heating by the heating module 1 after the temperature of the preheating region reaches the temperature range indicated by the temperature condition. Alternatively, after the temperature of the preheating region reaches the temperature threshold indicated by the temperature condition, heating by the heating module 1 is stopped, and the temperature threshold is specifically within a predetermined temperature range and the temperature range A temperature threshold close to or equal to the maximum value at.

  In addition, the preheating area may be an area surrounded by a chamber inside a battery box of an aircraft, an intelligent robot, etc., and before inserting a battery and supplying power (battery discharge) to an aircraft, an intelligent robot, or the like. Relevant functional assemblies (controllers, heating elements, etc.) of equipment such as aircraft and intelligent robots perform the preheating operation of the battery in the battery box.

  Further optionally, the processing module 3 is further used to control heating of the preheating area by the heating module 1 when a trigger event for battery preheating is detected. That is, it is automatically detected whether or not the battery preheating function needs to be turned on.
